A 27 g block with a volume of 10 cm³ is cut exactly in half. What is the density of one half, Ari?
A 17.9 g block with a volume of 2 cm³ is cut exactly in half. What is the density of one half, Bo?
A 31.6 g block with a volume of 4 cm³ is cut exactly in half. What is the density of one half, Esme?
4.
What particle-level evidence shows a chemical change, Jun?
- Particles move faster
- Atoms regroup into new particles
- Particles spread much farther apart
5.
What happens to water particles when ice melts, Kira?
- They join into a brand-new compound
- Same particles, looser arrangement
- They split into new atoms
6.
Sugar dissolves in water. At the particle level, what happens, Luz?
- Sugar atoms are destroyed by the water
- Sugar spreads among water particles
- Sugar turns into water
7.
Milo says boiling water is a chemical change because bubbles form. Agree or disagree?
- Agree: boiling makes new atoms
- Disagree: steam is still water
- Agree: bubbles mean a new substance
8.
Noah says freezing water makes a new substance, ice. Agree or disagree?
- Disagree: ice is still water
- Agree: ice is a new compound
- Agree: its color changes
9.

Physical and chemical properties and changes. Every version has 10 questions, and the answer key prints on the second page.

I can sort changes as physical (same substance) or chemical (new substances), using particle drawings as evidence.
I can name signs of a chemical change: new color or smell, light, heat or a new solid.
I can tell physical from chemical properties, and intensive from extensive ones.
I can use mass conservation: rust weighs iron + oxygen, and a burning candle's mass leaves as gases.

Standard: none (FL)

physical change: A change in form or state with no new substance

chemical change: A change that makes new substances

chemical property: How a substance reacts, such as whether it rusts

intensive property: A property that doesn't depend on amount, like density

extensive property: A property that depends on amount, like mass

Your child divided volume by mass. Density is mass ÷ volume.

Your child took the oxygen away. In rusting, iron joins with oxygen, so the rust weighs iron + oxygen.

Your child halved the density. Cutting a block halves its mass and volume, so the density stays the same.

What is the most common mistake with physical and chemical properties and changes?

Your child divided volume by mass. Density is mass ÷ volume.
